Abstract: PURPOSE: To obtain rib guide stripe type semiconductor laser of excellent reliability, by growing active layer and the layer above thereof in the second stage, securing layer whereinto sides of active layer are buried utilizing aqueous phase epitaxial growth method in the first stage.  
     CONSTITUTION: Utilizing the first aqueous phase epitaxial method, n-type Al 0.3  Ga 0.7 As layer 9, p-type GaAs layer (active layer) 10, p-type Al 0.3 Ga 0.7 As layer 11 are grown in this order in succession on the n-type GaAs semiconductor substrate 8. After forming SiO 2  layer 19 on the above mentioned p-type layer 11, stripe form etching groove is established by etching p-type layer 11 selectively with depth reaching the surface of p-type GaAs layer 10. Employing solution which helps in growing active layer, p-type layer 10 is melted back until reaching n-type layer 9 in hydrogen gas atmosphere.  Then, at the same time when melting back process is finished, p-type GaAs layer 12, p-type Al 0.3 Ga 0.7 As layer 13 is grown in succession again, and crystal surface, together with the active layer which is thicker than the active layer initially grown are made into evenness.

Title: Reduction of wear of papermaking wire
Inventor: TAKADA KAZUYUKI
IPC: D21H17/67
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce wear of a plastic wire for papermaking and to extremely prolong a life thereof by carrying out the papermaking of a pulp slurry containing a filler formulated therewith after addition of alumina and/or zirconia having a specific average particle diameter to the pulp slurry containing the filler. SOLUTION: This method for reducing the wear of a papermaking wire comprises addition of alumina and/or zirconia having a particle diameter larger than the average particle diameter of a filter formulated with a pulp slurry but smaller than 50 μm to the pulp slurry containing the filter such as talc and kaolin, especially heavy calcium carbonate and precipitated calcium carbonate formulated therewith, and papermaking of the added slurry. The addition amount of the alumina and/or zirconia is 0.03-12 wt.% based on the filler formulated with the pulp slurry. The added alumina and/or zirconia acts as a runner in the contact of the paper with the plastic wire and reduces the wear by the abrasion.

Title: Rebound prevention device of sliding door
Inventor: GOTO TADASHI
IPC: E05F5/02
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To attenuate the inertia force of a sliding door on closing it by arranging a sash sheave urged by a spring, on the upper rail of the sliding door to transfer the door on the rail while bringing a wheel into contact with the underface of a lintel and pushing the wheel out of the rail when transferring the sliding door to a door stop column side. SOLUTION: A wheel 52 rides on the bottom wall 73 of a brake member 7 provided on a rail 6 in the vicinity of a door stop column 4 when a sliding door 1 is opened, and the wheel is pushed against the restoring force of a spring 55 by the pressing force and retracted into a casing. In this case, when the wheel rides on the bottom wall 73, the brake acts thereon and the sliding door 1 becomes heavy once in the opening motion but when it passes over the bottom wall 73, the wheel 52 rolls smoothly to open the sliding door 1. The brake also acts to attenuate the inertia force of the sliding door 1 when the wheel 52 rides on the bottom wall 73 on closing the door and the door 1 collides with the column 4 after the speed thereof has decreased. Further, the door is moved back by the reaction force but it is prevented from riding on the bottom wall 73 and brought to a stop at the position in a closed state. In this way, the sliding door 1 is prevented from being opened due to rebound thereof or from being naturally opened.

Title: Electrochromic element
Inventor: ITO TOSHIYASU
IPC: G02F1/1524
Filed: 1989-04-27
Abstract: PURPOSE:To eliminate the coloration reaction of color developing films even if irradiated with UV rays in the state of not impressing a voltage thereto and to prolong the life of the element by incorporating metal oxides having an electrical conductivity into the color developing films. CONSTITUTION:The oxidation color developing film 6 consisting of polyaniline, polypyrrole, etc., is laminated on one transparent electrode film 2a and the reduction color developing film 7 is formed on the other transparent electrode film 2b by binary vapor deposition of tungsten oxide and the metal oxide, such as tin dioxide, having the electrical conductivity. Electrons and holes are, therefore, generated in the tungsten oxide when the color developing film 7 is irradiated with the UV rays, but since the recombination speed is increased by the metal oxide, the electrons and holes are recombined before tungsten bronze is formed and the coloration of the color developing film 7 by the irradiation of the UV rays is suppressed. The generation of the coloration reaction in the color developing film 7 when irradiated with the UV rays is prevented in this way and the longer life is obtd.

Filed: 1988-05-06
Abstract: PURPOSE:To precisely restore a transmission pulse which is pulse width- modulated in a reception side by providing a flip flop which detects the edge of the transmitted transmission pulse and which executes a signal inversion processing in synchronizing with the edge detection. CONSTITUTION:When a transmission pulse signal (a) is inputted to a transmission port, a part of it is delayed by an integrating circuit, is turned into a delay signal (c), and is outputted to a Schmitt gate 4. The delay signal (c) is outputted to an exclusive OR gate 3 and an edge pulse signal (d) showing the front edge (leading edge) position and the end edge (trailing edge) of the transmission pulse signal (a) is generated, whereby it is transmitted from a transmission transistor 7 to a pulse transformer 8. The signals transmitted to the pulse transformer 8 are transmitted by a pulse signal from a transmission line 9, and it turns on and off a reception transistor 13. A restored edge pulse signal (e) obtained by inverting the edge pulse signal (d) is generated on the side of the collector of the transistor 13, and the flip flop 14 executes the inversion signal processing in synchronizing with the signal (e). The signal is outputted to a reception port from an output Q as a restored pulse signal (f).

Title: Speed responsive type steering gear
Inventor: KUMASAKA TOORU
IPC: B62D6/00
Filed: 1982-06-25
Abstract: PURPOSE:To prevent a lateral turning accident due to abrupt steering in high speed travel by varying control ratio of a steering wheel to wheels according to the travelling speed. CONSTITUTION:When the vehicle speed is increased to displace a slider 10 left, the width of a V-belt groove 12a of a driven pulley 12 is narrowed and a V- belt 13 is shifted upward as a whole. As a result, a V-belt groove 11a of a drive pulley 11 is widened so that the winding radii of the V-belt 13 around both pulleys 11, 12 are larger at the driven pulley 12 side and smaller at the drive pulley 11 side. The rotation transmitting ratio of the drive pulley 11 to the driven pulley 12 is represented by the reciprocal of the winding radius ratio of the V-belt 13 so that the rotation transmitting ratio is reduced as the vehicle speed is increased. Thus even if a steering wheel is steered abruptly in high speed travel, a steering column 6 is not so much rotated and thereby danger such as lateral turning of the vehicle can be avoided.
